Consciousness

I am a quantum physicist by training, and it is often remarked that quantum physics is incredibly hard to get one’s head around, as it is so counter-intuitive, however in my opinion the counter-intuitiveness of quantum physics pales into insignificance compared to trying to get one’s head around the concept of consciousness. There is nothing more counter-intuitive than trying to contemplate the concept that you (as a conscious entity) might not exist.
